Method for orange preservation

Abstract

The invention discloses a method for orange preservation, and belongs to the field of fruit preservation. The method comprises the following steps: performing ultrasonic extraction on Chinese herbal medicines, such as leaf of purple perilla, and concentrating, so as to obtain a concentrated solution containing natural antiseptic organic matter, such as fat and phenols, taking rice and rice polishing as carriers, feeding the concentrated solution into the rice, so as to be soaked, drying and grinding the rice, mixing the rice with the rice polishing, ensuring that effective components in the Chinese herbal medicines are absorbed on the surfaces of the rice and the rice polishing, ensuring that organic components in the rice and the rice polishing are infiltrated into the interior of an orange peel under the roast smoking action of roasted wood charcoal, and ensuring that a layer of dense membrane is formed between the inner membrane layer of the orange peel and flesh, so as to isolate the external air and achieve the purpose of orange preservation. The method effectively solves the problems that the traditional method is poor in preservation effect and toxic substance is easy to remain, and the method is safe and environmental-friendly, does not have poisonous substance residue, is not harm to human health, and has good preservation effect.

Description

technical field

[0001] The invention relates to a fresh-keeping method for oranges, which belongs to the field of fruit fresh-keeping. Background technique

[0002] Tangerine is a fruit of the Rutaceae Citrus genus. It is brightly colored, sweet and sour, and is a common delicious fruit in autumn and winter. Oranges are sweet and sour, cool in nature, enter the lungs and stomach meridians, have the effects of appetizing and regulating qi, quenching thirst and nourishing the lungs. Oranges are very nutritious, rich in vitamin C and citric acid, have the functions of beautifying and nourishing the skin, eliminating fatigue, etc., can promote laxative, lower cholesterol, and contain more than 170 kinds of plant compounds and more than 60 kinds of flavonoids, most of which are All are natural antioxidants. The rich nutrients in oranges have the effects of lowering blood fat and anti-atherosclerosis, which is of great benefit in preventing the occurrence of cardiovascular dise...

example 1

[0017] First pick 0.8kg of perilla leaves, 0.7kg of sage and 0.5kg of vanilla, wash them with clean water, and put them in a pulverizer for pulverization to obtain a pulverized mixture, then put the pulverized mixture in a flask, and then add 350mL The mass fraction is 35% ethanol solution. After mixing evenly, place the flask in an ultrasonic oscillator, conduct ultrasonic extraction at 60°C and 1.0 MHz for 2 hours, and filter to obtain the filtrate after extraction. Put the filtrate in a rotary evaporator to remove Ethanol, collect the remaining liquid, and place it in a concentration tank for concentration to obtain a concentrated liquid; then add the concentrated liquid to the rice at a mass ratio of 1:2, stir and mix at 300r / min for 30min, and then add rice to it after mixing Quality 1.0% 45° white wine, stirred for 40min, and stood still for 1h, then filtered to obtain the filtrate, spread the filtrate in a ventilated place to dry, put it into a ball mill after drying, an...

[0019]First pick 0.9kg of perilla leaves, 0.9kg of sage and 0.8kg of vanilla, wash them with clean water, and put them in a pulverizer for pulverization to obtain a pulverized mixture, then put the pulverized mixture in a flask, and then add 375mL The mass fraction is 35% ethanol solution. After mixing evenly, place the flask in an ultrasonic oscillator, conduct ultrasonic extraction at 65°C and 1.1 MHz for 3 hours, and filter to obtain the filtrate after extraction. Put the filtrate in a rotary evaporator to remove Ethanol, collect the remaining liquid, and place it in a concentration tank for concentration to obtain a concentrated liquid; then add the concentrated liquid to the rice at a mass ratio of 1:2, stir and mix at 400r / min for 35min, and then add rice to it after mixing Quality 1.6% 48° white wine, stirred for 45 minutes, and stood still for 2 hours, then filtered to obtain the filtrate, spread the filtrate in a ventilated place to dry, put it in a ball mill after dry...

[0021] First pick 1.0kg of perilla leaves, 1.2kg of sage and 1.0kg of vanilla, wash them with clean water, and put them in a pulverizer for pulverization to obtain a pulverized mixture, then put the pulverized mixture in a flask, and then add 400mL The mass fraction is 35% ethanol solution. After mixing evenly, place the flask in an ultrasonic oscillator, conduct ultrasonic extraction at 70°C and 1.2 MHz for 3 hours, and filter to obtain the filtrate after extraction. Put the filtrate in a rotary evaporator to remove Ethanol, collect the remaining liquid, and place it in a concentration tank for concentration to obtain a concentrated liquid; then add the concentrated liquid to the rice at a mass ratio of 1:2, stir and mix at 500r / min for 40min, and then add rice to it after mixing Quality 2.2% 50° white wine, stirred for 50min, and stood still for 2h, then filtered to obtain the filtrate, spread the filtrate in a ventilated place to dry, put it in a ball mill after drying, and ...
